Testing the logic started out OK. Creating a file on Cimbaoth, it was read by the Raspberry Pi, which then signaled the power controller to cycle power which it did.

However, after running a while, it was clear that the power was also being cycled on occasion when it was not commanded. This caused a need for more complex signaling between the Pi and the controller so it was harder to be misunderstood.

As of this point in time, the logic for recognizing a more complex signal, and for generating that signal, has been developed, but not yet added to the production controller.

Still having trouble with packaging

2016-12-05 08:11:02:

Got box to work (sort of), had been connected to a poor choice of
Raspberry Pi pin. But a new issue emerges. On boot, the RPi pin
is not an output, must be pulled up because it goes high in spite
of the PIC's weak pull-down. Once getit runs, it gets set low,
and a minute later the plug is pulled.
After about 20 seconds, the cycle starts all over.

Largely complete
commit 56e57f72d9b15bf1256c4f30ba4dd6a59e5bce3c
Still want to make a new branch with doxygen

2016-12-13 09:22:04:

Original firmware worked, however, power cycles every 30 minutes
without the Pi software running, so something else was signalling
the controller.
Moving to a more involved signal, where three pulses of specific
length are required to signal the controller to cycle power.

Test 100 watt amp

2016-09-12 10:49:37:

Repeater will initially be set for 20 watts. It is unknown at
this time whether the addition of an external amplifier will
result in excess desense. After the repeater is at the site, an
amp will be tested for coverage.
